92 NOVITATES ZOOLOGIOAE XXII. 1915. 



The species is ven- ranch like tfu/nlica, differiug chiefly in being less clouded 

 and by the dark shading on the underside. 



The appendages are easily recognised; the aedeagns is short (TT mm.), and 

 has a marked curvature, the only species with this character ; the loose shuttle 

 piece is very long (0-65 mm.), bnt is possibly attached at its near extremity ; the 

 cornnti are small, and not very numerous. The valves have beyond the harpes 

 parallel sides (for 1-3 mm.) and ronnded ends. The harpes are free for a very 

 short distance, and are so short that their free portion is triangular. 



Fruhstorfer calls this species insularis : see remarks under that species. 



There are specimens of nesopkila from Penang and from Borneo.

C. tagalica appears to be a rather widespread species and lias many varieties, 

 some of very large size, some very small, some with very wide black borders, some 

 with them very reduced, some in which the copper colour is very coppery, almost 

 red, others in which it is pale, almost golden. The species with which it is most 

 likely to be confounded are celebensis, nesophila, and egena. It may generally be 

 recognised, at least in the S, by the large amount of dark shading on the underside, 

 especially along the basal side of the jiostdiscal line. 



The cJ appendages are most characteristic, and are recognisable without a lens ; 

 they have the longest valves and the smallest aedeagns of any species. The 

 remarkable circumstance that the males of tagalica and the form palnwanica are 

 indistinguishable both in facies and as to the appendages, whilst the ? ? have brown 

 patches in tagalica and white in palawanica,, shows that this colour variation has 

 not such specific value in this genus as has been supposed, and in this case repre- 

 sents a dimorphism of the ? similar to that which occurs in other Lepidoptera. 



There is another similar case in the genus : C. tJietis has a ? with white 

 patches, but the form of tketis from Bougainville, in the Solomon Islands, and 

 from other localities in its south-eastern distribution, has a very different ¥ with 

 brown patches, and these are of a diiferent outline — so that, though the cj has not 

 diverged from thetis more than would amount to a geographical race, the ? has 

 diverged beyond what that aspect usually covers. 



In the case of palawanica the divergence has not gone so far, and may 

 be covered under some hypothesis suggestive of dimorphism, such as I have 

 referred to. 



palatvanica is a variety not of tht'tis bnt of tagalica ; that Staudinger placed it 

 as a variety of thetis was possibly due to his regarding tagalica as a variety of
